JOI-IN R. SHAW, OF RURAL VALLEY, PENNSYLVANIA.

Application led April 5, 1911.

To all whom t may concern.'

Be it known that I, JOHN R. SHAW, a citizen of the United States ofAmerica, residing at Rural Valley, in the county of Armstrong and Stateof Pennsylvania, have invented certain new and useful Improvements inTools, of which the following is a specification, reference being hadtherein to the accompanying drawing.

This invention relates to tools for splicing wires and electricconductors, and the object of the invention is to provide a novel toolfor cutting or shearing the ends of wires whereby the wires can beinterlocled to form a positive and non-leakable connection between twowires for an electric current.

My invention aims to provide a tool constructed upon the principle of apair of pliers, and to furnish a tool with detachable jaws foraccurately cutting the ends of wires, whereby the wires will fitrtogether and interlock to provide aplurality of contacting surfaces.

The invention will be hereinafter described in detail and claimed, andreference will now be had to the drawing wherein there is illustrated apreferred embodiment of the invention, but it is to be understood thatthe structural elements thereof are susceptible to such changes as fallwithin the sccpe of the appended claims.

In the drawing z-Figure l is a side elevation of a tool in accordancewith this invention, Fig. 2 is a vertical sectional view of a portion ofthe same. Fig. 3 is a plan of the female jaw detached. Fig. 4 is a sideelevation of the same. Fig. 5 is a plan of the male jaw detached. Fig. 6is a side elevation of the same. Fig. 7 is a plan of one of the heads ofthe tool. Fig. 8 is an elevation of a wire splice as accomplished by thetool, and Fig. 9 is a cross sectional view of the same.

A tool in accordance with this invention comprises two handles or levers1 and 2, the handle 2 'having the outer end thereof enlarged, as at 3and provided with a slot 4 to receive the enlarged portion 5 of thehandle 1, said handle being of a size to pass through the slot 4 andthus permitof the handles being assembled. The enlarged portions 3 and 5of the handles 2 and 1 are pivotally connected together by a transversepin 6 extending through the enlarged portions 3 and 5. The outer ends ofthe enlarged portions 3 and 5 are provided with Specification of LettersPatent.

ings 13 for screws 14 adapted to screw into l the openings 9, saidscrews having the heads thereof counter-sunk in the jaw. The inner sideof the jaw is provided with a longitudinal tongue 14a adapted to fit inthe groove 8 and prevent lateral displacement, `and'the outer face ofthe jaw is provided with a central transverse groove 15. The bottom ofthis groove is stepped or provided with longitudinal ribs 16 and 17, therib 16 relatively to the side walls of the groove 15 being of a greaterheight than the rib 17, for a purpose that will presently appear. Thejaw 1l adjacent to the inner edge thereof is provided wit-h alongitudinal groove 18 intersecting the ribs 16 and 17 andlongitudinally alining with the openings 19 adjacent to the inner edgeof the aw 11.

4The head 7 of the handle l is provided with a male jaw 20 having screwopenings 21 and dowel pin openings 22 similar to the 11, and on itsinner face provided with a longitudinal tongue 23 adapted to engage inthe groove 8 of the head 7. The inner face of the male jaw 20 also has atransverse groove 24'an`d the bottom of this groove is stepped thereverse of the groove 15, as at 25. The front side of the jaw 2O has anextension 26 and said extension has the under side thereof stepped tolongitudinally aline with the stepped portion of the groove 24. One ofthe ribs of the eX- tension 26, designated 27 serves functionally as acutting device for the end of a wire, this particular rib entering theinnermost groove 28 of the jaw 11. lVhen a piece of wire is placed inthe openings 19 and the groove 18 and the jaws closed, the extension 26immediately cuts the outer surface of the wire, whereby the wire willpresent a transverse groove 29 and shoulders 30, the wire beingsimultaneously cut by the rib 27. Vhen the jaws are opened and the wireremoved the cut end of a wire may have iins 31, and to remove thesefins, the c011- fronting sides ofthe handles l and 2, adj a* cent to theenlargements thereof, are provided with arms 32 adapted to engage thepiece of wire and compress the fins 3l suiiiciently to provide a smoothsurface upon the wire. Another wire is similarly out by the tool andthen the cut endsof the wires can be placed together, as shown in Fig. Swhereby .the groove 29 of one wire will re ceive the rib 32 of the otherwire and the shoulders 30 of both wires abut. The interlooked-ends ofthe wires can then be fused,

wrapped or otherwise permanently con-- neeted.

The tool in its entirety is made of strong and durable material and canbe made of various sizes.

Vhat I claim is L A tool of the type described comprising pivotedhandles, heads carried by the outer ends of said handles, jawsdetachably connected to said heads, one of said jaws having a grooveformed therein and openings adapted to' receive a piece of wiretransversely of said groove, and an extension carried by the other jawand adapted to enter said groove and cut a piece of wire held by saidjaw to provide the same with shoulders whereby two cut pieces of wirecan beinterlocked.

2. A tool of the type described comprising pivoted handles, headscarried by the outer ends of said handles, jaws detachably connected tovsaid heads, one of said jaws having a transverse groove formed therein,ribs carried by the bottom of said groove, said jaw having openingsformed therein to receive the end of a piece of wire, and an extensioncarried by the other said jaw and adapted to enter said groove and cutthe piece of wire held by said jaw and provide the same with shoulders,substantially as described. Y

3. A tool of the type described comprising pivoted handles, jawsvdetachably connected to the outer ends of said handles, one of saidjaws having a transverse groove formed therein and openingsadapted toreceive a piece of wire, and an extension carried by the other aw andadapted to enter said groove and provide the wire held by the other jawwith shoulders whereby two kwires can be interlocked.

4. A tool of the type described comprising handles, having the outerends thereof pivotally connected together, heads carried by the pivotedends of said handles, a male jaw detachably connected to one of saidheads, a female jaw detachably connected to the other said head, saidfemale jaw having a transverse groove formed therein, longitudinal ribsupon the bottom of said groove, said female jaw having openings formedtherein whereby a piece of wire can be arranged transversely of saidgroove, an extension carried by said male j aw and adapted to enter thegroove of said female jaw, a depending rib carried by said eXtension andadapted to out the end of the wire mounted in said female jaw, saidextension having the bottom thereof shaped to coperate with the ribs ofsaid female jaw in providing the piece of wire with shoulders, wherebytwo wires similarly cut'oan be interlocked, substantially as described.

5. A wire cutting tool comprising two pivotally-connected handles, jawscarried by the outer ends of said handles, one of said jaws being'a maleand the other a female jaw, the female jaw having a transverse grooveand provided with wire-receiving means, the wire being received in thejaw longitudinally of the latter, a cutting rib carried by the bottom ofsaid transverse groove, and a cutter carried by the male jaw, saidcutter' being received when the aws are closed in the transverse grooveof the female jaw and cooperating with the rib of the female jaw toprovide the wire with a transverse groove.

6. A wire cutting tool comprising a pair of handles pivotally-connectedtogether, one of said jaws having a transverse groove and provided withwire-receiving means, ribs carried by the bottom of said groove; an eX-tension constituting a cutter carried by the other jaw for entering saidtransverse groove to engage the wire and provide the latter with atransverse groove, and a outting rib carried by said cutter to cut thewire transversely.

7. A wire cutting tool comprising a pair of pivotally-connected handles,jaws carried by the outer ends of said handles, one of said jaws havingwire-receiving means and having a groove extending transversely of thewire-receiving means, and a cutter carried by the other jaw to bereceived in j said groove as the jaws are closed, said cutter havingmeans to provide the wire with a transverse groove and also to cut thewire transversely.
